Concept explainers
Three students are discussing their results from part B:
Student 1: I think that the image is closer to me than the pencil itself. The closer something is, the bigger it looks. Because the image of the pencil appears wider than the pencil itself, the image must be closer to me than the pencil.
Student 2: That sounds reasonable, but when I used parallax to determine the location of the image of the pencil, I found that it was farther from me than the pencil.
Student 3: “That doesn't make sense though. If the image were behind the pencil, then how could see the image? Wouldn't the pencil block my view of the imager?"
Do you agree or disagree with each of these students? Discuss your reasoning with your partners.

- Use image below, i have attempted 3 times and I keep getting it wrong For #1 part a the answer is NOT 43.6, 34 or 48.9 For #1 part b the answer is NOT 1.4,1.76 or 1.22arrow_forwardHello, can you help me with me with part a, part b and part c, and can you label which one is one, thank you so mucharrow_forwardLabel the information that you know about each part of the diagram, and identify what you are trying to find.arrow_forward
- Hello, I really need help with part A,part B and part C because I don't know why I keep getting the wrong answer and I tried everything is there any chance you can help me with Part A,Part B, and Part C and can you label them as wellarrow_forwardIf we view a star now, and then view it again 6 months later, our position will have changed by the diameter of the Earth's orbit around the sun. For nearby stars (within 100 light-years or so), the change in viewing location is sufficient to make the star appear to be in a slightly different location in the sky. Half of the angle from one location to the next is known as the parallax angle (see figure). Parallax can be used to measure the distance to the star. An approximate relationship is given by d = 3.26 p , where d is the distance in light-years, and p is the parallax measured in seconds of arc. Vega is a star that has a parallax angle of 0.13 second. How far is Vega from the sun? Note: Parallax is used not only to measure stellar distances. Our binocular vision actually provides the brain with a parallax angle that it uses to estimate distances to objects we see. (Round your answer to two decimal places.) light-yearsarrow_forwardA baseball hit just above the ground leaves the bat at 24 m/s at 45 degrees above the horizontal. How far away does the ball strike the ground? Can you visually show the above. It has to do with right angles and trigonometric functions, but I need your explanation to understand how this works, as I am new to this.arrow_forward
